Title (EN) IMPLANT HAVING MEANS FOR FIXATION TO A BODY LUMEN AND METHOD FOR IMPLANTING THE SAME
(FR) IMPLANT FIXE DE MANIERE AMELIOREE DANS UNE LUMIERE DU CORPS ET PROCEDE POUR POSER LEDIT IMPLANT
Abstract:
(EN) A device for improving fixation and sealing of a prosthetic component when implanted in a body lumen during laparoscopic, endovascular, or open surgical procedures. In one embodiment, the prosthetic component comprises a graft having a hem defining an interior space. Enclosed within the space is an absorbent cord. The cord expands as it comes in contact with body fluids. The expansion due to the absorbed fluids forms a seal closely following the irregular shape of the lumen and improves fixation at the junction of the body lumen and the prosthetic component. Hem and cord arrangement also used to improve fixation of one prosthetic component to another in a modular graft. In another embodiment, an attachment tab has one part affixed to the outer periphery of the graft and another part attached to an area adjacent to the body lumen upon implantation, to resist forces tending to move the implant.
(FR) L'invention concerne un dispositif pour améliorer la fixation et l'étanchéification d'un composant prothétique implanté dans une lumière du corps pendant des procédures laparoscopiques, endovasculaires ou chirurgicales ouvertes. Dans un mode de réalisation de l'invention, le composant prothétique comprend un implant présentant un ourlet définissant un espace intérieur dans lequel est enfermé un cordon absorbant. Ce cordon augmente de volume lorsqu'il vient en contact avec des liquides organiques. L'augmentation de volume due à l'absorption des liquides provoque la formation d'une garniture d'étanchéité, dont la forme suit étroitement la forme irrégulière de la lumière, et améliore la fixation au point de jonction entre la lumière et le composant prothétique. L'ensemble ourlet-cordon sert également à améliorer la fixation d'un composant prothétique à un autre dans un implant modulaire. Dans un autre mode de réalisation de l'invention, une patte de fixation présente une partie fixée à la périphérie extérieure de l'implant et une autre partie fixée à une zone adjacente à la lumière après la pose de l'implant, afin de résister aux forces tendant à déplacer l'implant.
